2021 Informal Hearings

Dear Property Owner;

Starting September 13th and ending on September 24th, Ottawa County will be holding informal hearings; you may call (419) 734-6721 or visit room 203 to discuss value changes for the 2021 triennial update. These hearings will be held from 8:00 AM to 3:30 PM, Monday through Friday for this 2 week period. You may come in without an appointment, however if you have several parcels we may need to set an appointment at a later date, this is due to time constraints.

For CAUV questions you can visit room 202 or call (419) 734-6855.

If visiting, please stop in the hall on the second floor and talk to your county auditor, Jennifer Widmer, she will be greeting and directing the flow of visitors.

If your value is within a reasonable range of market value no action is necessary.
